Answer:
np > 10, and n(1 – p) > 10.
Step-by-step explanation:
The normal approximation is used when np>10 and n(1-p)>10.
Here, sample size=n=100 and p=0.42.
So,
np=100*0.42=42>10
n(1-p)=100(1-0.42)=100*0.58=58 >10
As, np>10 and n(1-p)>10 so, the normal distribution can be use to approximate the probability that more than 38 of the sampled people had their most recent eye examination in the previous year.
No it is not. The factors of 81 are 1,3,9,27...
